IMPROVEMENT IN CARPET-BEATERS.

Specification forming part of Letters Patent No. 143,155, datedSeptember 23, 1873; application filed August 20, 1873.

To all whom t may concern:

Beit known that I, JAMEs HoTEERsALL, of the city, county, and State ofNew York, have invented a new and Improved Carpet- Beater; and I dohereby declare the following to be afull, clear, and exact descriptionthereof, which will enable those skilled in the art to make and use thesame, reference being had to the accompanying drawing forming part ofthis specification, in which drawing- Figure 1 represents a longitudinalvertical section of this invention. Fig. 2 is a plan or top View of thesame.

Similar letters indicate corresponding parts.

This invention relates to an improvement in that class of carpet-beaterswhich I have described in my patent dated December 17, 187 2, N o.134,059. My present invention consists in the arrangement of swinginglevers for supporting the cross-bars in the ends of the oscillatingbeatingarms, which are provided with stops for regulating the extent ofthe motion of such swinging supports in such a manner that thecross-bars will yield to a certain extent when brought to bear on thecarpet, and, by their inherent gravity, the same will return to theirformer or original position when raised therefrom.

In the drawing, the letters A A designate beating-arms, which aremounted on a shaft, B, that has its bearing in the upright O of theframe of the beating-machine. An oscillating motion is imparted to suchbeatingarms A by meansof a crank-rod D. In the open ends of saidbeating-arms A are levers E, which swing on a pivot, a, and the outerends of which `are secured to cross-bars F, which serve to beat thecarpet; and, by means of such swinging supports, the cross-hars F willgive way when brought in contact with the carpet, and thereby thetexture of such carpet remains uninjured in the operation of beating.When. the cross-bars F are raised from the carpet, by meansof theirswinging supports E, such supports rest on padded cross-pieces b b inthe ends of the beatingarms. Stops c c, which are secured to raisedprojections on the ends of said beating-arms A, serve to regulate thedistance of the ascending cross-bars, by the contact of the stop withthe cross-bar on the descending end of the beating-arms. Said crossbarsE are also padded at their point of contact with the stops c, so thatthe working of the cross-bars or beaters on the ends of the beating-armsis comparatively noiseless, and, besides, a saving in material isefected, none of the parts being injured by contact with each other.

What I claim as new, and desire to secure by Letters Patent, is

The swinging levers E for supporting the cross-bars F, in combinationwith the oscillating beatingarms A having the stops c c, substantiallyas and for the purpose specified.

This speoilication signed by me this 14th day of August, 1873.
